Ever wanted to reprogram Arduino without a Computer? Have a look at the [Teague Labs] tutorial.
The Computerless Arduino consists of two major components; an Arduino-compatible microcontroller loaded with a realtime code interpreter, and a stand-alone 5 button LCD display to display port values and manipulate code. The display can be connected to the Arduino via a 4-pin port at any time to peek at In/Out values, view the current code, and make changes as desired.
By keeping the display separate, it’s possible to have many dedicated Arduino modules (we’re using one of the smallest, cheapest, and most-capable Arduino clones, the Teensy2.0 for $18), without needing to spend much on each additional device. For the display we’re using the super small uLCD-144 (by 4D Systems for $29), and the system could easily be modified to use a larger display or computer if desired.

Wonderful Arduino video sampler from [giekes.nl] (At the moment in its 1 bit / 1 and half bit stage) . The project is based over [TVout] library, [Video in on TVout] and [Ram library and 23k256 circuit]. Amazing job.
If you dig the 8-bit style colourful site you’ll discover several other video oddities based on Arduino (or at least Atmega328), well explained and referenced by the [Gijs Gieskes].

The Parallax Serial RFID Card Reader, from the Maker Shed, is a great way to add hardware based authentication into your next project. This easy to use board requires only 4 connections to your PC or Arduino. The RFID Reader Module can be used in a wide variety of hobbyist and commercial applications, including access control, automatic identification, robotics, navigation, inventory tracking, payment systems, and car immobilization. Check out Make: Projects for Riley Porter’s great RFID tutorial! (note: RFID tags and jumper wires not included)
